Upgrade the Cluster Agent Using Kubernetes CLI

  1. Download the target version of the Cluster Agent bundle from the Downloads portal.
  2. Unzip the bundle and change the directory to the unzipped folder.
    CODE 
    unzip appdynamics-cluster-agent-alpine-linux-<version>.zip
cd appdynamics-cluster-agent-alpine-linux-<version>
  3. Update the cluster-agent.yaml to include any previously applied configuration.
  4. (Optional) If you require the Splunk AppDynamics SaaS integration with Splunk Observability Cloud, check the required configurations in the Install Splunk OTel Collector Using Cluster Agent.
  5. Update the image tag to add the version of the downloaded Cluster Agent bundle (for example, 25.2.0):
    CODE 
    apiVersion: cluster.appdynamics.com/v1alpha1
kind: Clusteragent
metadata:
name: k8s-cluster-agent
namespace: appdynamics
spec:
appName: "<app-name>"
controllerUrl: "http://<appdynamics-controller-host>:8080"
account: "<account-name>"
# docker image info
image: "docker.io/appdynamics/cluster-agent:25.2.0"
serviceAccountName: appdynamics-cluster-agent
  6. Delete and re-create the Operator and Cluster Agent.
    CODE 
    kubectl delete -f cluster-agent.yaml
kubectl delete -f cluster-agent-operator.yaml
kubectl create -f cluster-agent-operator.yaml
kubectl create -f cluster-agent.yaml

Upgrade the Cluster Agent Using the Helm Chart

The latest Cluster Agent Helm Chart is available at appdynamics-charts/cluster-agent

  1. Use helm get and helm show to determine if an upgrade is required to install the most recent Cluster Agent images from appdynamics-charts/cluster-agent .
    CODE 
    # which images are currently installed by my release?
helm get all "<my-cluster-agent-helm-release>" -n appdynamics | grep -E 'agentTag|operatorTag'
agentTag: 21.12.0
operatorTag: 21.12.0
# which images are available to install?
helm show values appdynamics-charts/cluster-agent | grep -E 'agentTag|operatorTag'
agentTag: 21.12.0
operatorTag: 21.12.0
  2. To perform the upgrade, uninstall and re-install the Cluster Agent Helm Chart using the same namespace from the previous installation:
    1. (Optional) If you require the Splunk AppDynamics SaaS integration with Splunk Observability Cloud, check the required configurations in the Install Splunk OTel Collector Using Cluster Agent.
    2. Uninstall existing helm chart.
      CODE 
      helm uninstall "<cluster-agent-helm-release>" --namespace appdynamics
    3. Delete all the previously installed CustomResourceDefinition (CRDs) related to Splunk AppDynamics Agent by using these commands:
      CODE 
      kubectl get crd | grep appdynamics
kubectl delete crd clusteragents.cluster.appdynamics.com
kubectl delete crd infravizs.cluster.appdynamics.com
    4. Install Cluster Agent helm chart by using the same namespace.
      CODE 
      helm install -f ./ca1-values.yaml "<my-cluster-agent-helm-release>" appdynamics-charts/cluster-agent --namespace=appdynamics
